A. STBAUSE,

BUBBLE-BLOWER.

To all whom it may concern:

Be it known that I, FRANK P. BLAIR, a

citizen of the United States, residing at Los Angeles, in the county ofLos Angeles, State of California, have invented a new and usefulBubble-Blower, of which the followin is a specification.

his invention relates to bubble blowers provided with a combined airpressure and liquid reservoir, and it is the object of my invention toprovide a device, whereby soap bubbles may be continuously blowntherefrom until the liquid in the reservoir becomes exhausted.

It is a further object of my invention to provide such a bubble blowerconstruction that will render it impossible to accidentally liberate orspill the liquid contained in the reservoir.

I accomplish the above object by means of the device described herein,and illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of my bubble blower in operation. Fig. 2is a side elevation of the bubble blower. Fig. 3 is acentral verticalsection through the bubble blower illustrating the method of ejectingbubbles therefrom. Fig. 4 is a modified form of the air tube. Fig. 5 isa modified form of a bubble blower illustrating a modified arrrangementof the air inlet and outlet tubes.

Heretofore in blowingfsoap bubbles, pipes of various kinds have beenemployed thereby necessitating the employment of a dish of soapy waterfor the use 'of the bubble blower. Usually in the case of children thedish is often upset and the contents scattered around, resulting ininjury to carpets, draperies, and other furnishings of the room in whichthe water is being used.

By means of my invention I obviate the above mentioned disagreeablefeatures of bubble blowing by constructing a device in which the bubbleforming liquid is contained in a receptacle which is provided with anair inlet thereto, and an air outlet therefrom,

constructed in such a manner that it will bel impossible to accidentallyspill the liquid contained in the reservoir.

Referring more specifically to the drawings 5 designates a hollow ligurewhich may be formed of any configuration, having two bores 6 and 7 Thisfigure may be construct- Specification of Letters Patent.

ed in two parts of metal pressed into the proper form and'crimped orsoldered together after the insertion therein of the bub- `ble blowingmeans, or may be formed of celluloid or other similar material.

The bubble forming means consists of a continuous tube 8 flattened atone end as at 9 to form a mouth piece, and expanded into a cone or othersuitable shape at the other end as at 10, so that when the soapy film isforced outwardly therefrom it can be blown to a considerable size beforedetachment from the end of the tube. Tube 8 is preferably bent atapproximately the center' thereof as at 11, into a -U shape, as clearlyshown in Fig. 3 of the drawings, and then bent Voutwardly and downwardlyto the expanded end 10. Tube 8 is also provided with an air inletopening 12 that opens into the interior of a liquid and air pressurereservoir 13. Below opening 12 tube 8 is bent or vchoked as at 14 toclose the air passage therethrough. In place -of being bent, 'a plug l5may be inserted as shown clearly in Fig. 4 of the drawings. Directlybelow bend 14 is another opening 16 which'is preferably of double thediameter of the air inlet opening 12, through which the soapy film isforced to form the bubble on the end 10 of pipe 8.

In practice the liquid or soapy water for blowing bubbles is poured inthrough the opening 10 until the reservoir is approximately filled tothe lower end of the bend of tube 8,- as clearly shown in Fig. 8 of thedrawings, or if desired it may be siphoned through pipe 10 by theoperator. After the liquid has been drawn into the reservoir the bloweris in condition for operation, which is as follows: The figure is firstshaken slightly so that the liquid may enter the tube through theopening 16 and form a film thereover. The blower then blows air gentlyinto the reservoir 13 and this will expand the air in the reservoir 13thereby forcing the film upwardly through tube 8 and outwardly therefromand expanding it into the form of a bubble. This may be continuedrepeatedly until ail the liquid in the reservoir is entirely exhausted.

In Fig. 5 is illustrated a modified form of -my improved bubble blowerin which the tube 8 is divided into two parts 17 and 18. Tube 17 entersat the rear ofthe figure and terminates a short distance from the innerend of tube 18, there being a continuous pasn la sage through tube 17.The inner end of tube 18 is closed as at 19 and is provided with anopening through which the soapy ilm is forced by air pressure into theform of bubbles.

The modified form illustrated in Fig. 5 will not accomplish any betterresults than the form illustrated in Fig. 3, but is shown to illustratethat the pipe 8 may be .divided into two parts thereby dispensing withthe bent portion 14 or the plug 15 shown in Fig. 4 without departingfrom the spirit of my invention. The action in this form issubstantially the same as in the preferred form, the air being forcedthrough tube 17 creates pressure in the reservoir 13 thereby forcing thefilm of soapy water contained in the reservoir 13 upwardly and outwardlythrough tube 18 in the form` of bubbles.

By bending the tube 8 into a substantially U-shaped form the liquidwithin the hollow yfigure 5 will be trapped therein, thus obviatingaccidental leakage when the generator is not in use.

What I claim is:

1. A soap bubble blower, comprising a hollow body forming a combinedliquid receiving and air pressure chamber, and a tube mounted in saidchamber, the outlets of said tube terminating exteriorly of said body,said tube being choked intermediate its ends and having an air inlet andbubble outlet aperture one on either side of said choked portion.

2. A bubble blower, comprising a hollow body forming a liquid receivingand an air pressure chamber, and a tube mounted therein, that portion ofsaid tube inclosed within said chamber being provided with apertures,

the opening through said tube being closed between said apertures toprevent air from being forced continuously through said tube.

3. A soap bubble blower, comprising a hollow body forming a liquidreceiving and air pressure chamber, a tube mounted therein, said tubebeing bent in an approximately U shape within said chamber, that portionof said tube inclosed within said chamber being provided with aplurality of apertures, the opening through said tube being closedbetween said apertures, whereby when air is forced into said chamber thepressure created therein will force bubbles from the discharge end ofsaid tube.

4. A soap bubble generator, comprising a hollow body member forming acombined liquid receiving and air pressure chamber, and an air inlet andbubble -outlet tube mounted in said chamber, the said tube being bentwithin said chamber' to form a liquid trap.

5. A soap bubble generator, comprising a hollow body member forming acombined liquid receiving and air pressure chamber, and an air inlet andbubble outlet tube mounted in said chamber, said tube being bent'withinsaid chamber to form a liquid trapwhereby accidental leakage of liquidfrom the hollow member will be prevented when the generator is not inuse.

In witness that I claim the foregoing I have hereunto subscribed my namethis second day of September, 1913.
